+ 273890
---------
```

Step-by-step addition:

Align the numbers by place value:

```
3832854

---------
```

Add column by column from right to left:

- Units: 4 + 0 = 4
- Tens: 5 + 9 = 14 → write 4, carry 1
- Hundreds: 8 + 8 + 1 = 17 → write 7, carry 1
- Thousands: 2 + 3 + 1 = 6
- Ten thousands: 3 + 7 = 10 → write 0, carry 1
- Hundred thousands: 8 + 2 + 1 = 11 → write 1, carry 1
- Millions: 3 + 0 + 1 = 4

So:
